It has long been a practice in the building industry to constructcertain types of doors in such a manner that a large upper-panel areamay be quickly adjusted to present either a glazed window or an openscreened window.

The various methods of construction heretofore provided have been veryunsatisfactory for several reasons. For instance, a common method hasbeen to slide the glazed panel in a pocket formed in the lower portionof the door. This method is not an economical one and presents seriousdifficulties in the matter of preventing water from entering the pocketor the inner side of the door, Again, the nature of the construction issuch that the glazed sash is not easily removed and replaced.

It is one object of the present invention to provide a structure that isso constructed and arranged that no pocket of the character indicated isrequired; that provides a perfectly waterproof and weather proofstructure when the glazed sash is in a closed position; that is soconstructed and arranged that no parting bead is required, that will notrattle, and wherein the sash may be quickly and easily removed from, orreplaced in, the frame or casing proper.

Finally, it is an object of the invention to provide a structure of thecharacter indicated that will be economical to manufacture, thatrequires but little alteration in the standard door structure, that maybe quickly and easily adjusted to any required screened opening, andthat will be strong, durable, and highly efficient in its practicalapplication.

In the drawing:

Figure 1 is an elevation of a door embodying my invention.

Figure 2 is an enlarged elevation of the casing and sash taken at A inFigure 1, parts being broken away.

Figure 3 is a sectional view at 33 of Figure 2.

Figure 4 is a right edge elevation of the portion A of Figure l enlargedto full-size.

Figure 5 is a full-size sectional view through the structure taken at5'5 on Figure 1, partly broken away.

Figure 6 is a detail section at 56 on Figure 5, with parts broken away.

Figure 7 is a full-size elevation of a portion of the sash and itscasing taken at B of Figure 1.

Figure 8 is a detail elevation of the sash catch in operative position.

Referring more particularly to the drawing, the door proper is indicatedat I, the sash casing at 2, and the upper and lower sash at 3 and Alrespectively.

The casing 2 is a unitary rectangular frame proportioned to fit snuglyin the opening 5 in the upper portion of the door. In one edge'of theopening is seated a plate 6 having an inwardly turned flange l, and onthe outer face of the opposite edge is a keeper 8. An overbalanced arm 9is pivotally mounted on the casing 2 as at Iii to normally hang asshown. The casing 2 is fitted into the opening 5 back of the plateflange l and then the arm 9 is swung into engagement with keeper 8. Thisarrangement renders the casing easy to remove from the opening 5 andeasy to replace therein. The casing 2 is formed of sheet metal. Across-section through one side is typical of a cross-section taken atany point in the casing, and shows a rectangular box-like formation witha slot II on its inner side. The slot II is continuous throughout theinner periphery of the casing.

Through the outer peripheral wall of the Casing, and on one side only ofthe casing, are formed a number of spaced slots l2 for the purposehereinafter described.

The sashes 3 and 4 are identical in construction, therefore but one willbe described in detail.

The sash 3 is formed of sheet metal to provide a carrying frame for theglass I3, and is so proportioned that it will slide freely in the slotll, cooperating with sash 4 to substantially fill said slot wherever thetwo sashes pass each other, without any intervening parting bead.

At suitable points in the casing springs as H are inserted between thesash and easing wall. These springs are placed so as to bear against thesash and urge it into contact with the opposite edge of the slot. Sincesaid edge has only the thickness of the sheet metal of which the casingis made it permits the sash to slide freely and easily thereon, and yetthe sliding joint so made is perfectly weather proof.

When the two sashes 3 and 4 are in their closed positions their bottomand top rails respectively overlap as shown in Figure 6. Since they fitsnugly between the opposing edges of the slot ll they form a weatherpoofjoint between them, and they cannot rattle.

To hold the cash 3 in a completely closed, or a partially closedposition, its top portion is made sufiiciently wide to receive a memberl5 in which is formed a slot l6. A bolt I1 is mounted in the slot l5 andresiliently supported therein by a spring 18. The bolt carries a fingerpiece [9 projecting through a slot 20 in the face of the sash. When thesash is moved upwardly the bolt I! will engage the slots l2, being urgedinto engagement therewith by spring I8. The bolt is bevelled on its topedge to permit the sliding movement of the sash, but is flat on thebottom so that it may stay in engagement with any slot it engages untilretracted by a backward pull on finger-piece I 9.

The finger-piece l9 also functions as a lift for the corner of the sashat which it is placed, and a corresponding lift is fixedly mounted onthe other top corner of the sash as at 2|.

Since the two side edges of the sash do not necessarily contact thesides of the casing, there being some play between them, the top sashdoes not readily remain in its uppermost position without additionalsupport, therefore I form a protuberance 22 punched inwardly at the topof the side casing wall to engage the sash. When the sash is closed thebolt-and-slot engagement "-42 supports corner A and formation 221supports corner B.

By making the casing 2 as described it may be quickly and easily removedfrom the opening in the door, and when so removed the central portionsof the sides may be spread apart sufficiently to permit either sash tobe removed therefrom and replaced therein.

Although but one specific embodiment of the invention has been hereinillustrated and described, it will be understood that variousalterations in the details of construction and mode of application andassembly may be made without departing from the scope of the inventionas indicated in the accompanying claims.

I claim:

1. In a structure of the character described, a window casing comprisinga one-piece metal channel member having a substantially flat outer wall,parallel laterally and inwardly directed front and rear walls, andopposed inturned flanges on said front and rear walls parallel to saidouter wall and defining an inner wall, said flanges being in registryand terminating in spaced relation to form sash bearing edges, sashengageable resilient means in the channel for urging an engaged sashagainst the adjacent flange bearing edge to provide a seal, and saidwalls and flanges having inherent resiliency whereby to allow expandingseparation of the flanges and walls at the mid portions of the casingsides sufiicient to permit insertion or removal of a sash thereat.

2. The structure of claim 1, and a pair 0 sashes in mutual slidingcontact disposed between said sash bearing flanges in sliding engagementagainst the edges thereof.
